Little Painful Javascript Quirk

May 14th, 2006 Playing with SAJAX (AJAX framework for php, ruby etc.) I found an interesting quirk. Keep this in mind while using SAJAX (unless you have already found it (or want to find) the hard way).

July 4th, 2006 List of high quality javascript compressors. Feel free to add to this list in your comments.

August 12th, 2007 Trim is a useful function available in languages like Java & PHP which removes the leading and traling whitespace(s) from a String. Unfortunately Javascript doesn't natively provide trim functionality to the String object.

November 13th, 2005 Behaviour promotes itself as "the missing link for your AJAX apps". It allows you to use CSS selectors (like id or class) to apply Javascript behaviors to your HTML elements.

March 17th, 2006 Javascript doesn't natively support trim on strings. It is however very easy to implement with regular expressions.

July 26th, 2007 You would be surprised to know that the biggest Internet Explorer issue I am facing while writing rather complex cross-browser javascript code is related to just a comma. In javascript array if you add a comma after the last element in the array then Internet Explorer fails with a variety of undecipherable (Microsoft style) error messages.

May 15th, 2006 Sajax is an useful ajax framework to simplify ajax based development for languages like PHP, Ruby etc. Not many realize Sajax can be used equally well from plain old html pages (as in .html or .htm).

February 17th, 2006 Yahoo released an UI library for web applications, developed using Javascript and AJAX. It provides some nifty components like dual-calendar, tree, drag-and-drop, slidedrs etc.

May 17th, 2006 Google has released GWT - a java window toolkit which converts your java applications (using the toolkit API) to javascript (incl. AJAX) and HTML.

May 14th, 2006 Strangely you cannot set browser window status bar using javascript (by setting window.status) in Firefox. There are two simple ways you can enable it.

February 7th, 2007 As a javascript developer using onload often you will find that other script authors too love to use onload. Unfortunately onload accepts a function name and your reassigning will prevent others from using onload.

May 14th, 2006 This blog is being flooded with P0ker spam comments. Obviously they aren't getting through.

November 12th, 2007 AdBlock Plus is a controversial Firefox plugin to prevent ads from displaying on web pages. There is a simple procedure to detect (and take appropriate action) AdBlock Plus.

November 18th, 2005 This piece of JavaScript assigns a pageview to any click on a link - the pageview is attributed to the filename you specify. For example, to log every click on a particular link to www.example.com as a pageview for "/outgoing/example_com" you would add the following attribute to the link's <a> tag: <a href="http://www.example.com" onClick="javascript:urchinTracker ('/outgoing/example_com');"> It is a good idea to log all of your outbound links into a logical directory structure as shown in the example.

February 12th, 2004 Challenge: Resizing applet from within Java code. For example say the applet code calculates that the applet needs more space than it has been allocated, then how to go about it? Last time when faced with this problem I solved it with a nifty piece of Javascript method.
